Exposure to radioactive elements or having them through drinking water causes many biological risks. Therefore, it is important to investigate the drinking water especially in regions where people depend on well water for drinking. Concentrations of radon in Arar city of Saudi Arabia were measured by using RAD7 and RAD H2O accessories. Concentrations of radon were measured in three types of drinking water: mineral water, tap water and bottled drinking water coming from wells. The results showed that the average values of radon concentrations of all three water types under study were in the internationally permissible range. Results therefore showed that there were no indications of hazard in water samples and the investigated wells from which the water was taken are suitable for drinking concerning the measured radon. The work recommends more studies to investigate other radionuclide elements that might be present in the drinking water.
Key words: radon, water, RAD7, RAD H2O accessories, environment.
